SAM CLI (Beta)

Join the SAM developers channel (#samdev) on Slack to collaborate with fellow community members and the AWS SAM team.

sam is the AWS CLI tool for managing Serverless applications written with AWS Serverless Application Model (SAM). SAM CLI can be used to test functions locally, start a local API Gateway from a SAM template, validate a SAM template, fetch logs, generate sample payloads for various event sources, and generate a SAM project in your favorite Lambda Runtime.

Invoke functions from known event sources such as Amazon S3, Amazon DynamoDB, Amazon Kinesis Streams, etc.
Start local API Gateway from a SAM template, and quickly iterate over your functions with hot-reloading
Validate SAM templates
Get started with boilerplate Serverless Service in your chosen Lambda Runtime sam init
